Natural Orifice Endoscopic Transgastric Distal Pancreatectomy, A Prospective Randomized Controlled Trial. Natural orifice surgery may represent a paradigm shift in the area of minimally invasive surgery and therapeutic endoscopy. However, studies to date have been limited primarily to small ca...se series with small sample sizes. There has been no large rigorous randomized controlled trial of natural orifice surgery to date. Early work on procedures such as peritoneoscopy, oophorectomy and tubal ligation, while pioneering, have reproduced laparoscopic procedures with minimal morbidity and mortality. In contrast, distal pancreatectomy has a post-operative morbidity of more than 50% even in high volume tertiary care centers. As a highly morbid surgery, the post-operative event rate would allow for a significant difference to be seen in a trial of conventional versus NOTES distal pancreatectomy. We have recently completed a prospective randomized controlled trial of NOTES versus laparoscopic distal pancreatectomy in a swine model which builds on our earlier non-survival work. This video focuses on the endoscopic technique.
Excision of breast cancer that is visible only on mammogram. diagnosis is typically established on stereotactic biospy and excision is done with wire localization. This techniques involves localization by sonography of the hematoma that is left behind at the time of biopsy. It provides not only accu...rate location of the tumor but ensures adequate margins of excision.
A 49-year old female patient complainig of cough. X-ray and chest CTscan showed a 2.5cm nodule in the left upper lobe. Transthoracic biopsy was consistent with adenocarcinoma. PET-Scan and CT Scan showed no mediastinal disease. The procedure was performed through three incisions.
